The article discusses the significance of copper recycling in reducing carbon footprint and supporting a decarbonized economy. The study focuses on modeling copper recovery from secondary sources like waste electrical and electronic equipment using pyrometallurgical processes. Life cycle assessments of three scenarios were conducted, showing that conventional copper production can reduce carbon footprint by 71-96%. Moreover, the use of green hydrogen in copper recycling processes can achieve even higher reductions, up to 93-97% compared to primary production. However, the article highlights a crucial finding that using hydrogen produced with grid electricity can increase the carbon footprint, emphasizing the importance of integrating renewable energy sources for low-emission copper production. The research underscores the necessity of transitioning towards sustainable practices in metal supply chains to support the energy transition and promote a cleaner industry.
